Explanation:
Reconstruction was the period in the united states during which the Civil war took place and the laws were made to provide equity to the slaves ending slavery.
The problem arises due to the reunion of the 11 states of the South to the Union which seceded earlier. Slavery was more practised in the Southern states compared to Northern states.
The Republican party did corruption from 1869 to 1877 which allowed due to which they lost their election of 1877.
In 1877, a special electoral commission was established in favour of Hayes and Democrats took benefits of this condition.
When Hayes was selected, he withdrew the federal troops from the South which allowed the Democrats to gain their seats in South and ended Reconstruction.
1. The arrangement of the phospholipids that make up the cell membrane is referred to as the _______
2. A carbon atom has 6 protons but has 7 neutrons this carbon atoms would be called a _______
Answer: 1. phospholipid bilayer 2. This is carbon-13, an isotope of carbon
Explanation:1. Two layers of phospholipid form the membrane, with their hydrophilic ends inwards. The hydrophobic surfaces protect the cell from osmotic changes by isolating the cytoplasm from the environment - except for embedded transport mechanisms for moving ions and molecules in and out as required.
2. C-13 is a rare, stable isotope of carbon, making up about 1% of natural carbon.
An element is defined by the number of protons in the nucleus, because the number of protons is matched by the number of electrons in the nucleus, and it is the electrons that determine chemical properties. Nuclei with more than one proton (i.e. not H) also have neutrons, which have no charge. They assist in keeping the positive protons together in the nucleus and are important for stability. Atoms of an element can have different numbers of neutrons, more than one of which can be stable. This variants are called isotopes. They behave the same chemically, but have some different physical characteristics due to size difference.
There are minimum and maximum limits to the number of neutrons that form stable isotopes. Beyond those limits, the atoms tend to decay through radioactivity. For example C-12 and C-13 are stable isotopes. Another natural isotope C-14 is radioactive.
There is also a limit to the number of protons that can be held together by any number of neutrons. Uranium, with 92 protons, has only radioactive isotopes, but U-238 (146 neutrons) decays much more slowly than U-235 (143)or U-234 (142).

what happens to the body cells if the kidney produce very little urine?
Explanation:
Having filtered out small essential molecules from the blood - the kidneys must reabsorb the molecules which are needed, while allowing those molecules which are not needed to pass out in the urine. Therefore, the kidneys selectively reabsorb only those molecules which the body needs back in the bloodstream.

how are things transported through the membrane
Answer:
The mechanisms of transport across the cell membrane are as follow: 1- simple diffusion, 2- facilitated diffusion, 3- primary active transport and 4-secondary active transport
Explanation:
The cell membrane is a selectively permeable structure capable of transporting substances by different mechanisms. Simple diffusion is a type of passive transport (i.e. does not require energy) where non-polar molecules (e.g. O2, CO2) pass across the membrane by a process that does not require energy from the cell. Facilitated diffusion is another type of passive transport where larger polar molecules (e.g., glucose and amino acids) pass across the membrane by using specific transmembrane integral proteins. On the other hand, primary active transport is a type of active transport that uses chemical energy (e.g., ATP) to move substances such as metal ions (Na+, K+, Ca2+) across the cell membrane against their concentration gradient. Finally, secondary active transport is another type of active transport where transporter proteins are used to couple the movement of ions (e.g., H+ protons) down their electrochemical gradient to the transport of another ions/solutes against their concentration/ electrochemical gradient.

3. True or false: Science aims to answer TESTABLE claims.
Answer: True
Testable claims, or verifiable claims, are claims where we can prove them true or false. We do so by gathering/observing data, then afterward we see if the data fits the claim or not. If not, then we adjust the claim or we throw it out entirely.

Several factors determine the distribution of biomes on the planet. Which factor is considered most important?
A. weather
B. temperature
C. altitude
D. precipitation
Answer:
B
Explanation: i hope this is the answer
From the equator to the poles, the temperature of the Earth's surface normally drops. A biome's moisture content is influenced by both precipitation and evaporation, hence option B is correct.
What are biomes?Climate is the most important abiotic factor affecting the distribution of terrestrial biomes.
Temperature and precipitation are the primary determinants of plant growth. The plant will be discovered at that temperature and precipitation will be determined by the biome's temperature.
A biome's climate is mostly determined by the forms of life that exist there. Latitude, geographic characteristics, and atmospheric processes that disperse heat and moisture are only a few of the variables that affect climate. Scientists disagree on the number of distinct biomes that exist.
Therefore, temperature determines the distribution of biomes on the planet.

A DNA molecule with the base sequence A-G-C-T-C-A was used as a template for the synthesis of
a messenger RNA molecule. Which base sequence correctly represents the corresponding portion
of this RNA molecule?
Answer:
A-G-C-U-C-A
Explanation:
A-G-C-U-C-A is the base sequence correctly represents the corresponding portion of RNA molecule if DNA molecule with the base sequence A-G-C-T-C-A was used as a template. It is because the RNA molecule is formed from the same bases used in DNA except thymine. In RNA molecule, instead of thymine, uracil is attached with other nucleotide bases.

how cellular transport is beneficial to cells, and how it play a role in homeostasis and why is transportation across the cell membrane (active, and passive) is important to maintaining homeostasis, and cellular activities.
Answer:
Explanation:
Cell transport refers to the movement of substances across the cell membrane. Probably the most important feature of a cell's phospholipid membranes is that they are selectively permeable. A membrane that is selectively permeable, or semipermeable, has control over what molecules or ions can enter or leave the cell, as shown in Figure below. This feature allows a cell to control the transport of materials, as dictated by the cell's function. The permeability of a membrane is dependent on the organization and characteristics of the membrane lipids and proteins. In this way, cell membranes help maintain a state of homeostasis within cells (and tissues, organs, and organ systems) so that an organism can stay alive and healthy.
